Hi

I'm a really a new with this cross platform development, so I have some dumb
questions, which I hope you can help me with. If there is a better newsgroup
for this question, please point me to it.

I have written a Win32 application in Delphi. Some of the most platform
depended features I can think of is user themes support (not XP themes) and
audio playing.

The application, must be made to run on Unix, Linux and Mac OS X. To me it
seems I have theses choices:

- Rewrite the application in Java.

- Rewrite the application to .net.

- Rewrite the application using a cross platform framework like wxWidgets or
Qt.

I would of course like to reuse as much of the Delphi code as possible:

I know Delphi has support for .net, but I don't how much this can help me.

I also know that a cross platform (object) Pascal compiler exists, again I
don't know how much this can help me.

I'm thinking that some of the GUI in depended code could be compiled to a
platform depended library, would this be a good idea?

What solution would you recommend me to take, and do you have any links book
titles to good updated information about this subject?
